Williams-Sonoma Essentials of Baking book recipe. This cake came out very delicious and taste great with a cup of coffee. Just a couple of words of wisdom to newbie bakers: Always sift your dry ingredients (this helps make your cake lighter instead of denser). Make sure your eggs and butter are at room temp (otherwise your cake would not be as smooth). Follow instructions/measurements PRECISELY! Grease and flour your pan very well (this will help very much when it comes time to removing the cake from the pan). Have all your ingredients on hand and read the recipe before beginning (take it from me, you don't want to end up skipping a step or missing an ingredient because you rushed thru it). Do not open the oven while it is baking. Invest in buying a pastry blender. Always let the cake cool in the pan the indicated time or your cake will fall apart to pieces if you remove it to soon from the pan. This recipe requires atleast 3 medium-large mixing bowls. The following ingredients include one recipe for streusel and one recipe for the cake batter.
